Le 11 septembre 2015 De 10h30 à 12h00 Simona MEI Observatoire de Paris We will present recent results on the evolution of very massive galaxies in the field and in dense environments (e.g. galaxy clusters), using recent data from the HST/CANDELS and COSMOS surveys. We will...
Le 7 juillet 2015 De 10h30 à 12h00 Klemens BÖHM Karlsruhe Institute of Technology Many scientific databases nowadays are publicly available for querying and advanced data analytics. One prominent example is the Sloan Digital Sky Survey (SDSS) SkyServer, which offers data...
Le 26 juin 2015 De 10h30 à 12h00 Nicolas BOULANGER Université de Mons We intend to give a brief introduction to the key issues in higher-spin gravity, a theoretical model that generalises gravity to include an infinite tower of higher-spin gauge fields. The main reference...
Le 25 juin 2015 De 12h30 à 13h30 Geraint LEWIS University of Sydney Is the universe fine-tuned for life? And if it is, what does this mean? I’ll summarize some of the key parts of a book that I am completing on this topic, showing that it with a little change to the laws...
Le 19 juin 2015 De 10h30 à 12h00 Jonathan CHARDIN IoA, Cambridge I will present cosmological radiative transfer simulations of Hydrogen reionization calibrated with a range of measurements of the Lyα opacity from QSO absorption spectra. I will show that the Lyα opacity is...
Le 12 juin 2015 De 10h30 à 12h00 Martin FEIX Technion & IAP Spatial variations in the distribution of galaxy luminosities, estimated from redshifts as distance proxies, are correlated with the peculiar velocity field. Comparing these variations with the peculiar...
Le 5 juin 2015 De 10h30 à 12h00 Mathieu BARTHELEMY IPAG, Grenoble Les aurores polaires sont des phénomènes lumineux visibles généralement autour des pôles. Ces phénomènes sont présents sur Terre mais également sur d'autres planètes. Nous aborderons les...
Le 1 juin 2015 De 10h30 à 12h00 Jason SteffenNorthwestern University NASA's Kepler mission has revolutionized the field of exoplanets and its discoveries give new insights into our theories of planet formation and dynamical evolution. With over 4000 planet candidates and 1000...
Le 21 mai 2015 De 10h30 à 12h00 Amphithéâtre de la Grande Coupole Michel MAYOR Observatoire Astronomique de l'Université de Genève During the last 20 years, an important fraction of the 2000 exoplanets presently known have been discovered by Doppler spectroscopy. ...
Le 24 avril 2015 De 10h30 à 12h00 Hervé WOZNIAK Observatoire astronomique de Strasbourg Double-barred galaxies account for almost one third of all barred galaxies, suggesting that nuclear/inner stellar bars, which are embedded in large-scale primary bars, are long-lived...
